📖 Vocabulary

There are 160+ thematic vocabulary sets covering every major IT domain — from beginner-level Git and Agile terminology to advanced topics like LLM architecture, Kubernetes operators, and FinTech protocols. New sets are added regularly.

Start with General IT Terms for the foundations, then move to your primary tech stack. Backend developers benefit most from Backend Development, API Design, and Database sets. Frontend developers should prioritise the CSS & Frontend and JavaScript & TypeScript sets.

Each vocabulary set contains 5–7 questions mixing definition matching, fill-in-the-blank sentences, contextual usage, and multiple-choice exercises. Every answer includes a detailed explanation with related terms and real usage examples from code reviews and documentation.

Beginner sets focus on terms you'll encounter daily regardless of role — Git basics, Agile vocabulary, JSON/YAML. Intermediate sets cover role-specific terminology. Advanced sets tackle specialised domains like distributed systems consensus, AI safety, quantum computing, and enterprise architecture.

Yes. There are dedicated sets for Product Management, Engineering Manager, Business Analyst, Scrum Master, Freelance & Contractor, and Technical Writer roles. These focus on the communication and domain vocabulary unique to each position.

IT vocabulary includes technical acronyms (SLO, RBAC, mTLS), compound nouns (backpressure, dead letter queue), verbs used as nouns (a deploy, a merge), and collocations (push a commit, raise a ticket, spin up a container) that don't exist in general English dictionaries.

Some vocabulary exercises include phonetic transcriptions (IPA). For dedicated pronunciation practice — including how to say cache, nginx, kubectl, daemon, mutex, and YAML — visit the Pronunciation exercises section.

New vocabulary sets are added in regular batches. Recent additions include sets for AI Agents, WebAssembly runtime, eBPF, data mesh architecture, and quantum computing. Check back or watch for "New" badges on fresh sets.

Yes — the DevOps & Cloud set covers CI/CD, containerisation, infrastructure-as-code, and cloud services terminology. For deeper coverage, also study the Kubernetes Deep Dive, Terraform & Infrastructure-as-Code, Observability & Monitoring, and Cloud Architecture & FinOps sets.
